RICHMOND — Redskins tight end Vernon Davis can pantomime shooting a jump shot after touchdowns, but cornerback Josh Norman’s favorite big-play theatrics — pretending to shoot a bow and arrow — will remain off limits in 2017, despite the NFL’s decision to relax its restrictions on game-day celebrations.

That’s just one example of the fine line NFL officials will be tasked with drawing this season after NFL owners voted in May to loosen the league’s restrictive prohibitions after players and fans alike complained they took the joy and spontaneity out of games.

On Sunday, a delegation of NFL officials visited Redskins’ training camp to brief the media on the key rules changes and new points of emphasis in the rule book for 2017, airing a brief video to players and then fielding questions about gray areas. Such briefings are held at all 32 NFL teams’ training camps each August, as the preseason approaches.

The issue of what sort of celebrations are now legal — and what remain off-limits — is of concern to the Redskins and their fans, given the penalties Norman and Davis incurred last season. Norman was fined $10,000 for shooting a pretend bow and arrow after his fourth-quarter interception in a victory over Cleveland. And Davis was fined $12,514 for tossing up a jump shot over the goal post.

Carl Johnson, the NFL’s former vice president of officiating who in 2012 became the league’s first full-time official, summarized the key changes and fielded all questions. There were plenty about celebrations.

What’s new in 2017: Players will be allowed to use the football as a prop in their celebrations, but they can’t use anything other than a football as a prop. By way of illustration, Johnson said that a player could pretend to shoot a jump shot and that he also could pretend to “dunk” a ball over the goal post — so long as he didn’t hang on any part of the goal post, thus converting it to a prop.

Group celebrations and celebrations on the ground, such as making snow angels, are okay.

But any act directed at an opponent or deemed offensive or violent in nature remains a violation. That’s where Norman’s pantomime of shooting a bow and arrow would still get him in trouble, Johnson explained, because it is deemed violent — even if the imaginary bow and arrow is shot toward the sky, rather than at someone. And it’s a foul whether it’s on the field or on the sideline, he added, if officials see it.

Norman, reached after practice, said he didn’t understand the distinction the NFL was drawing.

“I don’t understand it,” Norman said, informed that the bow-and-arrow pantomime was still prohibited because the NFL deems it ‘violent in nature.’ “I can’t shoot a pretend bow and arrow, but when Tampa Bay fires off their cannon, that’s fine? That’s a hostile act.”

Johnson acknowledged that there is no clear, bright line for celebrations “deemed offensive” but added that it would including taunting, anything sexually suggestion and violent. That’s why the NFL hasn’t attempted to create a list of “offensive” celebrations, noting that if the league came up with 100 taboo behaviors, no doubt a player would come up with the 101st, unanticipated one.

“We can’t prepare for what all they have inside their creative minds,” Johnson said. The overall goal, he said, was to allow more spontaneous expression while maintaining standards of sportsmanship.
